On World Interferometry Day, TU Ilmenau is paying tribute to the invention of the interferometer, which can be used to measure the smallest quantities with high precision. At a scientific symposium, experts discussed key technologies of interferometry, while interested parties were able to experience the physical phenomenon live at the Night of Interferometry.
Whether in smartphones, microscopy or biomedical technology - interferometers can be used to measure exceptionally small quantities with high precision on the basis of light. With the invention of the interferometer more than 140 years ago, physicist Albert A. Michelson laid the foundation for numerous metrological applications - including the nanopositioning machine at the Institute of Process Measurement and Sensor Technology at TU Ilmenau, which is known worldwide for its precision. With the World Interferometry Day on April 9, the TU Ilmenau and SIOS Meßtechnik GmbH pay tribute to this invention - and this year is no exception.
International experts from science and industry came together at a symposium at TU Ilmenau, , to discuss current developments, applications and prospects for interferometry. Among other things, the focus was on reliable sensor technologies for autonomous driving, the use of digital holography in semiconductor measurement technology and interferometry in environmental protection.
Interested parties were able to experience the phenomenon of interferometry live at the Ilmenau Night of Interferometry at on the evening before the scientific symposium. Laboratory tours on nano-measuring machines, interactive information stands and a hologram exhibition brought them closer to the physical phenomenon. The evening concluded with a spectacular laser show. With his laser harp, Prof. Eberhard Manske brought the fascination of light to life in an impressive way.
